Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.

) ..........60NC/W
Junction-to-Case Thermal Resistance (B

) .................1NC/W
Note_1:
Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-
layer board. For detailed information on package thermal considerations, refer to
www.maxim-ic.com/thermal-tutorial.
Note_2:
The 48-pin TSSOP-EPR package has a top side exposed pad for enhanced thermal management. Connect this exposed
pad to an external heatsink to ensure the device is adequately cooled. The maximum power dissipation in the device is a
function of this external heatsink and other system parameters. See the
Thermal Information
section for more information.
